Applications of GIS: Disaster Management and Emergency Response01:29

Applications of GIS: Disaster Management and Emergency Response

452
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Manipulation and Analysis01:21

Manipulation and Analysis

283
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Methods of Obtaining Topography

278
Topography involves measuring and mapping land elevations, natural features, and artificial structures to create accurate representations of the terrain. Topographic surveying relies on traditional and modern methods, each with distinct advantages and limitations.Traditional Surveying Methods:Transit stadia surveys and plane table surveys were widely used traditional surveying methods. These techniques relied on instruments like theodolites and stadia rods for measuring distances and angles,...

Habitat Fragmentation02:31

Habitat Fragmentation

20.9K
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Levels of Use of a GIS01:29

Levels of Use of a GIS

346
Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Design Example: Alignment of a Road Line Using GIS

327
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Area of Science:

  • Ecological restoration
  • Geospatial analysis
  • Climate change adaptation

Background:

  • Mediterranean wildfires are increasing due to climate change.
  • Greece lacks a standardized system for post-fire restoration prioritization.
  • Existing prioritization tools may not fully integrate socio-ecological factors.

Purpose of the Study:

  • To develop and propose a flexible, scalable prioritization system for post-fire vegetation restoration in Greece.
  • To integrate stakeholder perspectives with geospatial data for enhanced restoration planning.
  • To identify high-priority areas requiring immediate attention for vegetation recovery.

Main Methods:

  • Qualitative interviews with 15 stakeholders to identify key restoration criteria.
  • Multi-criteria overlay analysis using Geographic Information System (GIS) and Remote Sensing (RS).
  • Integration of stakeholder-derived criteria with fire history, slope, and protected area status.

Main Results:

  • Identified 77.25 km² of areas for restoration based on integrated criteria.
  • Highlighted three specific locations totaling 31 km² requiring special attention.
  • Demonstrated the effectiveness of combining qualitative and quantitative data for prioritization.

Conclusions:

  • The proposed system effectively prioritizes burned areas for vegetation restoration.
  • Integrating stakeholder input enhances the socio-ecological relevance of restoration planning.
  • The flexible and scalable approach supports diverse organizations in optimizing restoration efforts.
